Introduction

2-in/2-out Thunderbolt™ audio converter

The audio converter uses Thunderbolt™, the latest generation of high-speed interface technology. With this, we have realized a system with low latency that was not possible using USB 2.0. Since it also supports recording and playback at up to 24-bit/192kHz, it can also be used for the playback of high-resolution sound sources delivered with superior audio quality over the Internet.

Attention to audio performance

The entire system reproduces the original audio faithfully. An asynchronous transfer system that is not impacted by computer jitter is used along with the latest AD/DA converter, which supports 192kHz.

Built-in high-performance mic preamps

The high-performance mic preamps are based on those developed for our H Series. Each input also supports Hi-Z connections. The gain can be raised by up to 60 dB, and +48V phantom power can be supplied.

dedicated mixer application

Use this application to make internal mixer and monitoring effect settings. For details about , see the ZOOM website (http://www.zoom.co.jp/downloads/).

Be careful not to allow foreign objects or liquids enter the unit.

Operating environment Do not use in extremely high or low temperatures.

Do not use near heaters, stoves and other heat sources.

Do not use in very high humidity or where it could be splashed by water.

Do not use in places with frequent vibrations.

Do not use in places with much dust or sand.

Connection cables and input/output jacks Always turn the power OFF for all equipment before connecting any cables.

Always disconnect all connection cables and the AC adapter before moving the unit.

Usage Precautions

Interference with other electrical equipmentIn consideration of safety, the has been designed to minimize its emission of electromagnetic waves and to suppress interference from external electromagnetic waves. However, equipment that is very susceptible to interference or that emits powerful electromagnetic waves could result in interference if placed nearby. If this occurs, place the and the other device farther apart. With any type of electronic device that uses digital control, including the , electromagnetic interference could cause malfunction, corrupt or destroy data and result in other unexpected trouble. Always use caution.

CleaningUse a soft cloth to clean the exterior of the unit if it becomes dirty. If necessary, use a damp cloth that has been wrung out well. Never use abrasive cleansers, wax or solvents such as alcohol, benzene or paint thinner.

Temperature considerationsContinuous use of this interface for long periods of time, for example, might cause it to become warm. This is normal as long as it does not become too hot to touch.

Breakdown and malfunctionIf the should malfunction or operate abnormally, disconnect it immediately. Then, contact the retailer where you purchased it or Zoom support and provide the following information: product model, serial number and details of the symptoms of malfunction or abnormal operation, as well as your name, address and telephone number.
